Bioresorbable hyaluronic acid alginate hydrogel use in total ankle arthroplasty to control post-operative scarring

End-stage ankle arthritis can be a debilitating condition, with ankle replacement as an avenue for significant pain relief and functional return to activity. However, peri-prosthetic scarring and ectopic bone formation are commonly observed following joint replacement surgery, and several methods of treatment exist to address these conditions post-operatively, with varied success. Maintenance of ankle joint range of motion has been shown to lead to lower pain and higher patient satisfaction following ankle replacement. Presented in this study is the use of a hyaluronic acid alginate hydrogel at the time of index surgery to decrease the risk of peri-prosthetic scarring.
